Table 2.

Quantifications obtained for the data in the three illustrations. For the comparison involving actual and linearly interpolated values (ALIV) and the average difference between successive observations (ADISO), the calculation performed is A minus B. The ADISO superiority percentage refers to the superiority of B over A, except for Retention for Participant 1008 (superiority of A over B).
